Merged-by: Michael Niedermayer <michaelni@gmx.at>
When all the codepaths using manually set .arch/.fpu code is
behind runtime detection, the elf attributes should be suppressed.
This allows tools to know that the final built binary doesn't
strictly require these extensions.

When OpenCL kernels are compiled, is_compiled flag is being set for each
kernel. But, in opencl uninit, this flag is not being cleared.
This causes an error when an OpenCL kernel is tried on different OpenCL
devices on same platform.
Here is the patch with a fix

a876585215 had the unintended side effect of returning AVERROR(ENOMEM)
when track->entry is zero, while the code intentionally wants to
continue in that case.

This mainly consists of replacing all the pointer arithmatic 'addiu'
instructions with PTR_ADDIU which will handle the differences in pointer
sizes when compiled on 64 bit mips systems.
The header asmdefs.h contains the PTR_ macros which expend to the correct mips
instructions to manipulate registers containing pointers.

There are no independant uses of mips32r2 instructions except for the
FPU parts. Due to the heavy use of mips32r2 specifc fpu extensions, I
am guessing the original author intended MIPSFPU to imply MIPS32R2 anyway.
Since these fpu instructions are available on mips64 (non-r2), enable them
there as well.
Also remove the last occurence of HAVE_MIPS32R2 (which is coupled to
HAVE_MIPSFPU anyway).
mips32r2 is left in the list of options form compatability so that using
--disable-mips32r2 doesn't break anything.

Removing these removes the dependency of this code on mips32r2 which would
allow it to be used on processors which have FPU instructions, but not r2
instructions (like the mips64el debian port for instance).

Instead, warn that bitrate will be clamped down to the maximum allowed.
Patch is mostly work of Kamendo2 in issue #2686, quite tested within that issue.

The only distribution which still uses it according to
https://trac.ffmpeg.org/wiki/Downstreams is "gentoo stable", but
http://packages.gentoo.org/package/media-video/ffmpeg lists stable as shipping 1.2.6 which is 6 point
releases behind. Also gentoos ffmpeg maintainer stated "don't worry about gentoo: we're in the process
of moving to latest 2.2 for stable."

The mov muxer already supports picking up extradata that wasn't
present during the avformat_write_header call - we just need to
propagate it. Since the dash muxer uses delay_moov, we have time
up until the first segment is written to get extradata filled in.
Also update the codec description string when the extradata becomes
available.

According to the WebP Lossless Bitstream Specification
"each transform is allowed to be used only once".
If a transform is more than once this can lead to memory
corruption.

SAMPLE-AES encryption is not commonly used yet, but without this patch
ffmpeg is thinking that the hls segments are not encrypted which
produces broken files.
